Updated to iOS 26!

EXPANDED FUNCTION LIBRARY
We've significantly expanded our mathematical coverage with 4 powerful new function types:
• Constant Functions showcasing horizontal lines and their fundamental properties
• Square Root Functions with domain restrictions and transformations
• Absolute Value Functions showcasing V-shaped graphs and their properties
• Advanced Rational Functions with numerator and denominator control

REVOLUTIONARY ARCHITECTURE REDESIGN
Complete codebase modernization delivers dramatically improved performance and reliability. The app now launches faster, responds more smoothly to interactions, and provides a more stable learning experience across all devices.

STUNNING VISUAL TRANSFORMATION
Every function type now features its own distinctive color palette and visual theme. The vibrant new design makes mathematical concepts more memorable and helps students quickly identify different function families.

COMPREHENSIVE HELP SYSTEM
Brand new contextual help system provides detailed explanations for every mathematical concept and app feature. Students can now access instant guidance on function properties, mathematical analysis, and visualization techniques.

ENHANCED HAPTIC FEEDBACK
Feel the mathematics through carefully calibrated haptic responses. Gentle feedback accompanies parameter adjustments while stronger vibrations mark important mathematical moments like zero crossings.

INTELLIGENT CODE ORGANIZATION
Behind-the-scenes improvements include streamlined file structure, optimized algorithms, and removal of legacy code, resulting in faster load times and more responsive user interactions.

DUAL PERSPECTIVE MASTERY
Seamlessly switch between y = f(x) and x = f(y) perspectives for deeper mathematical understanding. This feature particularly benefits students preparing for advanced calculus and inverse function concepts.
